CAST-l RON RAILWAY-SLEEPER.

SPECIFICATION forming part ofLetters Patent No. 304,622, dated September2, 1884.

Application filed May 26, 1884.

rah, Bengal, India, have invented a new and useful Improvement inCast-Iron Railway- Sleepers, (for which I have obtained a patent inGreat Britain, 'No. 2,490, dated June 28, 1877, and in India, datedNovember 6, 1876, No. 61,) of which the following is a specification.

My invention relates to a construction of cast-iron sleepers forrailways, which I will describe, referring to the accompanying drawings.

Figure 1 represents a longitudinal section, Fig. 2 a plan, and Fig. 3 anend view, of a sleeper according to my invention applied to adouble-headed rail secured in a chair; and Figs. 4, 5, and 6 arecorresponding views of a similar sleeper applied to a flanged railsecured by clips.

The sleeper consists of the oblong plate A, having the two longitudinalribs a a and the two transverse ribs b 12, forming between them arectangular space, in which is placed the block of wood B, constitutinga cushion for the rail R or its chair 0. The under side of the plate mayhave a transverse rib, as indicated at D. A socket, E, is provided atone (No model.) Patented in India November 6, 1876, No. Gl, and inEngland June i 1877, No. 52,490.

end of the plate to receive the tie-bar F, and it is convenient to havea similar socket at the other end, as indicated at E, so that if eithersocket should be broken the other may be used on turning the sleeperround.

For securing the tie-bar F-the cotter f and gib g are applied as shown;but the one being made a little wider than the other their positions maybe inverted where it is necessary to make a slight variation in thegage. The chair or clip bolts H are passed through both the plate andthe wooden cushion.

Having thus described the nature of my invention and the best way I knowof performing the same, I claim- A metallic railway-sleeper consistingof an oblong plate constructed on its upper surface with ribs for thereception of a block of wood to cushion the rail, and at its end withthe socket to' receive within it one end of a tierod, substantially asdescribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 21st day of April, A. D.1884:-
